Korobov was well known for creating some rather interesting fireamrs, such as the TKB-059, a three-barreled experimental assault rifle, and the TKB-408, a bullpup assault rifle meant to compete with the AK-47. While these weapons looked and felt rather promising, none of his weapons ever entered any form of service with the Russian Army; most, if not all, of these weapons can be now seen at the Weapons Museum at the Tula Kremlin.
